FLUID IMPELLER HOUSING ASSEMBLY Filed March 24, 1941 Y provide means forreceiving and holding clampingelements' 24. Each of these clampmechanlsms is 01' similar construction, the bracket-22 being formed withan inwardly converging radially disposed recess" opening outwardly andbea ing defined on its marginal sides by undercut surfaces}! to receivethe lugs 30 of substantially the size and shape of said recess and whichex-r tend inwardly from the clamp or'plate member 32 extending radiallyinwardly and in overlapping .and cantilevered relation to the marginalflange I! of the side plate assembly. Mountedbdja cent the inner end ofthe plate 32 isan adjustable bolt or set screw 34 adjustably engagingthe side plate assembly adjacent the flange [2 whereby the flange can beproperly seated, upon application of a turning movement to the set screw,with respect to the housing 2, thus providing a detachable connectionfor; the side plate assembly. The Joint between the side plateiassemblyand housing 2 maybe rendered fluid-tight by thereof if necessary becauseof wear or the like. These clamping mechanisms effectively hold the sideplate assembly in operative association with the housing and eliminatemachine work and tapping and other detailed finishing procedures whichhave been necessary heretofore where bolts, or similar elements, havebeen used for securing the side plate assembly to the housing, thuseliminating a large amount of machine work 'thereof. The plate 58 isdisposed in abutting reand greatly facilitating the placing of theside.plate assembly in position and removal of the same when that becomesnecessary;

'While the above described structure embraces characteristicsrecommending its ready acceptance ever present means for holding a sideplate assembly in. association with an impeller housing, neverthelessthe invention, in one of its preferred forms, is disclosed inFigures 4,5 and 6, embodying certain characteristics making it particularlyadapted for use under the environment disclosed. The invention accordingto Figures 4, 5 and 6 is embodied in a fluid impelling device ed to thehousing 35 and the web or flange 52 depending from the web and formingthe overhanging structure according to the disclosure.

i The clamping member is in the form of an outer plate 58 having aninwardly .and upwardly extending leg 60 forming a longitudinal groove 62between'the said plate 58 and the upstanding portion of the inwardlydisposed leg 80 adapted to receive, when the said clamp is in operativeposition with respect to the bracket 46, the downwardly' depending oroverhanging flange 52 lation to the bracket 46 and its positioning webor rib 48, and is provided with the spaced positionlng lugs 54 and 56laterally embracing the rib and the positioning lug or overhangingprojection which is disposed in overlapping relation to'the uppermarginal edge I0 of said positioning rib 45. Threadedly mounted in theopposite end of the plate 58 is a bolt or cap screw 12 which has its endin engagement with the annular or marginal flange 44 of the side plateassembly which, when tightened, fixes the plate in operativeassociatiorrwith the housing 38.

From the above description it will be apparent that the clamp iseffectively held in operative position at all times by its interfittlngand cantilevered relation with the depending flange 52 which provides ananchor resisting movement of the bolt 12 to effect a tight fit betweenthe side plate assembly and the housing. The clamp is effectivelypositioned at all times by positioning lugs 64 and 66 and held in radialposition between the leg and the overhanging'lugtfl. It will be notedthat the width of the groove between the plate 58 and leg 60 is somewhatgreater than the thickness of overhanging flange 52 to permit the clampto be placed into position and removed from association with the bracket46. This type of clamp structure provides-for quick manipulation of theside plate assembly either in the assembly or disassembly of the samewith respect to the housing, yet provides fora decrease in weight in theentire structure and the elimination corresponding substantially to thatshown in Figures 1 to 3, inclusive, and includes an impeller housing 38with a side plate assembly 38, stepped as at 40, to fit within anopening 42 of the impeller housing and providing an annular flange 44overlapping the housing 35, the said impeller housing enclosing animpeller corresponding substantially to that shown in Figures '1 to 3,inclusive, and operable in substantially the same manner. a v i V Inthis embodiment, a plurality of clamping mechanisms may be disposed incircumferentially spaced relation about the periphery of the housing 58and are of similar construction, one only being shown in the fragmentaryviews of Figures 4 to 6, inclusive. The clamping mechanism comprises acircumierentially extending bracket 46 having a centrallyfdisposed andradially extending rib or web 48 extendingoutwardly therefrom, andwhichbracket is constructed to provide a circumferentially and inwardlydisposed groove 50 formed between the opposed webs 52 and 5.4 and thetransversely disposed connecting web 56 therebetween. the web 54 beingdirectly connectof machine work on the housing and side plate assemblywhich has heretofore been necessary to effect a connection therebetween.In this form of clamp structure, the bolt 12 is maintained at all timesin proper operative association with the flange to maintain properassembld relation of the side plate and the housing, maintaining at alltimes a fluid-tight joint therebetween. As in the other embodiments, agasket may be provided between the side plate and housing. if sodesired. 7

While I have herein described and upon the drawingshown illustrativeembodiments of the invention, it is to be understood that. the inventionis not limited thereto but may comprehend other constructions,arrangements of parts, details and features without departing from thespirit of the invention.
